This could cause significant deterioration in the performance of the equipment, or lead to injury and electric shock. Do not replace the lamp immediately after the unit has been used. Allow a cooling period of at least one hour before replacement. The temperature of the lamp is still high, and may cause burn injuries. Do not subject the lamp unit to shock. Doing so may cause lamp blowout. Do not use a flammable air duster to clean the internal parts of the unit. Doing so may cause fire. Use only genuine replacement parts for the lamp unit. Also, never attempt to reuse an old lamp unit. This may cause the unit to malfunction. Do not touch the surface of a new lamp. Doing so may shorten the lamp life and cause lamp blowout. When replacing the lamp, be careful not to injure yourself as the lamp may be broken. When replacing the lamp of a projector suspended from the ceiling, work at height is required.
